The match was shifted indoors due to weather after Gibbs broke out to a 4-1 lead in the first set.

Saturday's contest was a rematch from earlier this year, when Gibbs took down Koroleva 6-2, 6-2 on Feb. 23 in Stanford's 5-2 neutral-site victory in Gainesville, Fla.

"I was a little concerned at first because the girl I was playing hits a really big ball, and that's her strength, so obviously indoors can favor that type of player," said Gibbs. "But I think after the first game or so, I realized that I could move her a little more easily on the indoor court, and I actually think the move to indoors made my job a little bit easier today in terms of getting her on the run."

Gibbs, who improved to 28-1 in May during her career, has now won 12 consecutive matches. The junior All-American closed out the 2011-12 campaign by winning 17 matches in a row.

Gibbs can also become the first player to capture the NCAA team and singles crowns in the same season since Duke's Mallory Cecil in 2009 at College Station, Texas.

She will next face No. 31 Breaunna Addison of Texas on Sunday in the semifinals. That match will not begin until at least 11 a.m. PT.
